iPad Increase Battery Usage Time

Same here. I am now getting 15 hours total which is about a week's worth of computing for me.

This came about after having a discussion with a colleague about services. His whole premise was that apps should be allowed to run in the background without you knowing. I argued there is already a definition for that and it is called a virus. Long story short, it got me thinking in terms of: if there is a service I don't need, kill it. Apple is very conservative about what services are allowed in their ecosystem which is a plus. But there are just myriads of things I don't care about.

 

For additional power savings....

If you don't use it, you can turn off Bluetooth.

If you don't travel, you can turn off Location (now called Privacy).
